OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 309,839, dated December 30, 1884.

Application filed July Q2, 1884.

To all whom t may concern.-

Be it known that l, FRANK Finir, of the city of Springfield, county of Clark, and State of Ohio, have invented certain new and useful Improvements in Oil-Oups, of which the following is a specification.

This invention relates to oil-cups, and has for its object to provide an oil-cup wherein the valve-seat is located in the cap of the cup, and wherein the valvestem is hollow and provided with outlet-ports, to allow the oil to be poured into the cup through the stem of the valve, said stem extending out through the cup, thereby preventing dirt and dust from entering` the cup when the valve is normally closed, and permitting the valve to be operated from the outside of the cup.

My invention consists in an oil-cup provided with a screw-cap having a valveseat, in combination with a valve having` a stem provided with a central opening in thedirection of its length, and outlet-ports in com munication th erewith, said stem extending through the cap of the cup, and being provided with springs to retain it in a desired position, substantially as hereinafter described.

It also consists in the combination, with an oilcup having a removable cap provided with a valve-seat, of a valve having a hollow stem extended through the removable cap, said stem being provided with a concaved head, and having outlet-ports in communication with the central openingv of the valvestem, and a spring to keep the valve normally seated, substantially as and for the purpose hereinafter described.

l't also consists in an oil-cup having a removable cap provided with a valve-seat, in combination with a valve the stem ot' which is provided with a central opening and outletports, said outlet-ports communicating with the central opening, and being so located upon the stem as to be closed when the valve is seated, and having air-vent openings communicating with the outer atmosphere, said airvents being cut into the valve-stem at its periphery, substantially ashereinai'ter described.

It also consists in the combination, with an oil-cup having a cap provided with a valveseat and a central opening, of a valve-stem provided with a removable valve at its lower (Nomndel.)

end and a concaved cap at its upper end, and having a central opening and outletports communicating therewith, and having airvents communicating directly with the outletports, to allow air to enterthe ports ata point in close proximity thereto, the said valvestem being provided with a spring, said spring being located between the concaved head of the stem and the cap ot' thc oil-cup, to keep the valve normally closed, substantially as hereinafter described.

Figure 1 represents in side elevation an oil-cup constructed in accordance with myinvent-ion, and Fig. 2 a longitudinal section of the same.

The base A ofthe oil-cup, of'nsual material, is provided with the oil-chamber B and outlet port or opening C, and is of ordinary construction. The cap D, provided with screwthreads, and adapted to be screwed int-o the base or main portion of the oil-cup,'is hollowed out at its interior, and has a depending valve-seat portion, E, which forms the seat for the valve F, said valve F being provided with a valve-stem, G, which is preferably screwed into the valve. (See Fig. 2.) The valve-stem G is provided with a central opening, H, which extends a portion of its length and communicates with outlet-ports I, which ports are provided with external air-vents, J, which normally extend to a point just above the cap D. The valve-stem G is extended out through the central opening of the cap D, said cap forming a bearing therefor, and is provided at its upper end with a concaved head, K, said concat-'ity converging toward the central'opening, H, of the valve-stem.

Located upon the valve-stem G, and between its head K and the cap D ot" the oil-cup, is a spiral spring, L, which keeps the valve F pressed normally against its valve-seat.

By the construction herein described I am enabled to turn oil into the oil-cup through the valve-stem, it being simply necessary to press the stem and valve down, so that the outlet-.ports may come to a pointjbelow the valve-seat, the air-vents allowing air to pass into rthe oil-receptacle.

The operation of manipulating the valve from the outside and doing away with a screwthreaded valve-stem is a great advantage.

I ain aware that oil-cups have .been in use wherein the valve-stem was provided with a head to abut against Jthe cap of the oil-cup lupon its interior to keep the dust fronrentering the cup, said stem being also provided with a spring; but Such valve-stem and valve were inconvenient to operate and more eX- pensive to manufacture.

The air-vents .I are made by cutting a channel or groove into the valve-stem from the outlet-ports I to a point above the cap D of the oil-cup.

I claiml. An oil-cup provided with a screw-threaded cap having a valveseat, in combination With a valve having a stein provided with a central opening in the direction of its length,

and outlet-ports in communication therewith,.

3. An oil-cup having a removable cap provided with a valve-seat, in combination with a valve the stem of which is provided with a central opening and outlet-ports, said outletports communicating with the central opening, and being so located upon the stem as to be closed when the valve is seated, as described, and having airvent openings, said air-vent openings being cut into the valvestem at its outside, substantially as and for the purpose set forth.

4. The combination7 with an oil-cup having a removable cap provided with a valve-seat, and having a central opening, of a smoothsurfaced valve-stem provided with a removable valve at its lower end, a concaved cap at its upper end` and a central opening and outlet-ports, said ports being provided with airvents communicating directly therewith to allow air to enter the oil-cup below the surface of the cap, the said valve-stem being provided with a spring Alocated between its head and the cap of the oil-cup to keep the valve normally closed, substantially as described.

In witness whereof I have hereunto set my hand and seal, at Springfield, Ohio, this 18th day ofJuly, A. D. 1884,

N. E. G. VHITNEY, I. J. CLEvnNG-ER.
